=== Special Note

* During a rebalance upgrade from 6.x (or any earlier version) to 7x, in mixed mode (where you are communicating with Couchbase Server whilst some but not all nodes are upgraded), there is a known issue where data may be written to the wrong location.
The solution is to either upgrade to 3.2.9, or to quiesce application processing so there are no writes until you have upgraded all nodes.
The solution is to either upgrade to 3.2.9, or to pause application processing so there are no writes until you have upgraded all nodes.
If you encounter a similar situation during migration and need help with mitigation, please contact our support team.

* Between bug fixes and performance improvements, the `ChannelConnectionPool` will be made the default in a future release.
